샤프트드라이브 자전거디자인 개발에 관한 연구

This study chose the bicycle, an eco-friendly transportation mean as the research center, and put forward a new bicycle driving system design proposal through researching about drawback and characteristics of existing Shaft-Driven bicycle. Progressing method: Understood and grasped the shaft driving system and features and so on, researched about the domestic and foreign development researches and related patent. As the result showing in the researches, most car shaft-driven researches were quoted as the related researches for bicycle and written to paper, and partial realm of patent mainly works on technology development. Therefore, the new Cross-head driving system was used to replacing Bevel-gear driving system and applied to the new Chinless bicycle design, through analyzing related materials of patent and getting advices from bicycle designers and experts as well. The 3D models, structural diagram and simulation model of bicycle with Cross-head driving system was worked out In the empirical study. An expert group, which was constructed by mechanical design experts from KIMM(Korea Institute of Machinery & Materials) and bicycle designers, evaluated towards the structure and design and gave the recommendation. And at last the final model was modified and worked out on the basis of above validation and recommendation. Furthermore, in this study, the Cross-head driving system was applied for Shaft-Driven bicycle design research; and it is possibile to be used as the basic reference for bicycle design vitalizations in future bicycle research.
